Microscopes

hospitals use microscopes for random stuff and other random stuff MLOL That is totally and utterly wrong. hospitals use microscopes for diffrent things, and what the hell is MLOL?? Hannah Russell works at the hosital and she smells :]

: Electron Microscopes are scientific instruments that use a beam of highly energetic electrons to examine objects on a very fine scale. This examination can yield the following information: ; Topography : The surface features of an object or "how it looks", its texture; direct relation between these features and materials properties (hardness, reflectivity...etc.) ; Morphology : The shape and size of the particles making up the object; direct relation between these structures and materials properties (ductility, strength, reactivity...etc.) ; Composition : The elements and compounds that the object is composed of and the relative amounts of them; direct relationship between composition and materials properties (melting point, reactivity, hardness...etc.) ; Crystallographic Information : How the atoms are arranged in the object; direct relation between these arrangements and materials properties (conductivity, electrical properties, strength...etc.)

The rough focusing knob on a microscope moves the objective lens or the stage closer to or farther away from the specimen in large increments. This allows you to quickly adjust the focus to get the specimen into view before using the fine focusing knob for precise focusing.

Microscopes use lenses to magnify objects, allowing small details to be visible. With higher magnification, the microscope can resolve objects that are very close together, making them appear as separate entities. This ability is key in studying the fine details and structures of tiny specimens.

Adjusting the body tube of a microscope allows you to focus on the specimen by changing the distance between the objective lens and the eyepiece. Moving the body tube up brings the specimen into focus, while moving it down takes it out of focus. This adjustment is key for obtaining a clear image.

Media can both mirror and magnify reality. In some cases, media reflects real-life events and trends accurately. However, media can also amplify certain aspects of reality, emphasizing specific messages, narratives, or elements for effect.

The term "jack knob" typically refers to a type of cabinet or drawer knob that has a cylindrical shape with a larger disc at the base. It is often used in furniture design for a classic and functional look.

A fluorescence microscope uses a much higher intensity light to illuminate the sample. This light excites fluorescence species in the sample, which then emit light of a longer wavelength. A fluorescent microscope also produces a magnified image of the sample, but the image is based on the second light source -- the light emanating from the fluorescent species -- rather than from the light originally used to illuminate, and excite, the sample. - I found a great link that compares this to conventional microscopes. Click the link below!

Compound microscopes (also called compound light microscopes) employ light and an array of glass lenses to magnify an object. (This is distinguished from a simple microscope of one lens.)

An electron microscope uses a beam of electrons to magnify an object. The lensing system employs electric and magnetic fields and is specialized for applications requiring much higher magnification.

The coarse adjustment knob moves the stage up and down quickly, while the fine adjustment knob allows for precise focusing.

This statement is incorrect. John Dalton was a British scientist known for developing the atomic theory in the early 19th century. The scanning tunneling microscope was invented much later, in 1981 by Gerd Binnig and Heinrich Rohrer.

The revolving nosepiece or turret holds the objective lenses in a microscope, and it can be rotated to change the magnification. This allows for seamless switching between different objective lenses without having to physically remove and replace them.

In a microscope, reflection occurs when the light hits the specimen and bounces back, allowing us to see it. Refraction happens when light passes through the lenses of the microscope, bending the light rays to focus the image. Both reflection and refraction play crucial roles in forming a magnified image of the specimen being observed through a microscope.

Really small things. Because there are limits to how small an object we can observe through a light microscope, we developed the electron microscope. By setting up a sample and streaming electrons at it to resolve an image, we can "see" things smaller than we'd be able to see through a light microscope.

The image taken from an electron microscope is called an electron micrograph or simply a micrograph. It provides a highly detailed and magnified view of the specimen being studied.

The two main enemies of a microscope are dirt and moisture. Dirt can obstruct the lenses and affect image quality, while moisture can cause fogging or damage to delicate internal components. Regular cleaning and proper storage can help prevent these issues.

Light intensity decreases as magnification increases in a microscope. This is because as the magnification increases, the same amount of light is spread over a larger area, resulting in reduced brightness. To compensate for this, microscopes may have adjustable light sources or specialized lenses to maintain adequate illumination at higher magnifications.

A transmission electron microscope actually sends electrons off of its' very very sharp point and through the sample. The current measurement between the tip and the stage, where the object being measured lies, is monitored. The tip is maneuvered to keep constant current. This movement is measured and equated to the surfaces' geometry. It can see in great detail the objects surface. It can be used in semiconductor makers fabs to look at what they have made.

A mirror or a condenser lens is typically used to reflect light into a microscope to illuminate the specimen being observed. The light source can be adjusted to control the intensity and angle of the illumination.

A transmission electron microscope (TEM) uses a beam of electrons to pass through a thin specimen to produce a high-resolution image. This type of microscope can achieve magnifications greater than what is possible with a light microscope, making it useful for studying the ultrastructure of cells and materials at the nanoscale.

There there are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, TEMicroscope, Dissection microscope, etc and most of them are used to see small cells that cannot be seen by the naked eye.

A light microscope creates a magnified image through a series of lenses. The light rays reflected from the viewed abject, pass through these many lenses and form an enlarged picture of the object. It is able to show the fine details of the object that most people are studying or looking for.

When you move the slide to the left while looking through a microscope, the image of the specimen on the slide will appear to move to the right in the field of view. This is because the light passing through the slide and specimen is refracted and magnified by the lenses of the microscope.

To carry a microscope, use both hands to securely grip the base and the arm of the microscope. Make sure the microscope is switched off, all components are secured, and carry it in an upright position to prevent damage to the lenses or internal components. It's also a good idea to place it in a padded carrying case for added protection during transportation.
